MODIS Fire Detection GIS Data:
MODIS fire detection data for the current year are compiled Terra and Aqua MODIS fire and thermal anomalies data generated from MODIS near real-time direct readout data acquired by the USDA Forest Service Geospatial Technology and Applications Center, University of Wisconsin Space Science and Engineering Center, University of Alaska-Fairbanks Geographic Information Network of Alaska, the NASA Goddard Space Flight Center Direct Readout Laboratory, and NASA Goddard Space Flight Center MODIS Rapid Response System. These data are provided as the centroids of the 1km fire detections and are a composite dataset compiled from the listed sources.

MODIS fire detection data for years 2000 to 2009 are Terra and Aqua MODIS fire and thermal anomalies data from the official NASA MCD14ML product, Collection 5, Version 1. These data are provided as the centroids of the 1km fire detections. GIS data provided in ESRI shapefile, coverage and geodatabase formats.

VIIRS-AF Fire Detection GIS Data:
VIIRS fire detection data for the current year are generated using the NASA VIIRS-AF fire detection algorithm with VIIRS near real-time direct readout data acquired by the USDA Forest Service Geospatial Technology and Applications Center, University of Wisconsin Space Science and Engineering Center, Oregon State University and the NASA Goddard Space Flight Center Direct Readout Laboratory. These data are provided as the centroids of the 750 meter fire detections and are a composite dataset compiled from the listed sources.

VIIRS I Band Fire Detection GIS Data:
VIIRS I Band fire detection data for the current year are generated using the University of Maryland VIIRS I Band fire detection algorithm with VIIRS near real-time direct readout data acquired by the USDA Forest Service Geospatial Technology and Applications Center, University of Wisconsin Space Science and Engineering Center, Oregon State University and the NASA Goddard Space Flight Center Direct Readout Laboratory. These data are provided as the centroids of the 375 meter fire detections and are a composite dataset compiled from the listed sources.

Landsat 8 Fire Detection GIS Data:
Landsat fire detection data for the current year are generated using the University of Maryland Landsat fire detection algorithm with daytime Landsat data acquired by NASA and the US Geological Survey and compiled by the USDA Forest Service Geospatial Technology and Applications Center. These data are provided as the centroids of 30 meter fire detections. Please note that availability of Landsat from the USGS is subject to variable latency, and temporary system anomalies, that may affect the completeness of this data product.

AVHRR and GOES Fire Detection GIS Data:
AVHRR and GOES fire detection data are not provided for download by the Active Fire Mapping Program. 1km AVHRR and 4km GOES fire detection data for the current year are accessible from NOAA/NESDIS SSD Fire-Web GIS website

User Note:
Please note that direct readout products are subject to temporary system anomalies that may affect the acquisition of satellite data by one or all of the listed sources and, consequently, the completeness of this data product. All near real-time GIS data are provided in ESRI shapefile and coverage formats and are updated hourly.
